Decks are used to calculate the weight of a load and this is measured in pounds. They also use decks for calculating cargo capacity, how many trucks can be loaded or unloaded at port terminals, and as an analytical tool for lifting loads onto trailers.

The “deck load chart” is a tool that allows users to calculate the weight of a deck. The deck load is calculated by multiplying the total square footage of the deck with the number of people on it.

For a total load weight of 55 pounds per square foot, use 40 lbs per square foot for live loads (varying loads that are dynamic, such as the weight of people and furniture) and 15 lbs per square foot for dead loads (the weight of the materials used to create the deck).

As a result, one can wonder how deck load capacity is calculated.

Start by determining the entire area of your deck and multiplying it by 50 psf to get the maximum load capacity. A 100-square-foot deck, for example, would be built to hold 5000 pounds. Don’t get confused about how much weight you should or want to put on the deck.

What is the live load on a deck, as well? The regulation stipulates that a residential deck must be constructed to withstand a minimum live load of 40 pounds per square foot. The external force exerted to a deck as a result of its usage is known as the live load. Under a live load, people, furniture, and any other moving, physical things on the deck are protected.

## What is the difference between a live and a dead load?

The dynamic forces resulting from occupancy and planned usage are referred to as live loads. They are the transitory forces that may pass through a structure or act on a specific structural element. The structure’s “gravity load” is equal to the combined dead and living loads. However, structures are subjected to additional loads.
